They won't pinch you and you won't find them on the beach. The name of the new radio-frequency crab cavities has nothing to do with their appearance and is merely illustrative of the effect they will have on circulating proton ...

Tapping into the quantum properties of photons for optoelectronics requires highly efficient light sources. Lead trihalide perovskite nanocrystals exhibit a number of properties that make them promising candidates as light ...

You probably didn't notice the gravitational wave that propagated through the Earth in the early morning of Jan. 4, 2017, but thanks to a sophisticated use of vacuum technology, a pair of extremely sensitive laser interferometers, ...

(Phys.org)—An international team of researchers has found that Neanderthals and modern humans both evolved in ways that allowed for better breathing through the nose in a cold climate. In their paper published in Proceedings ...

At its most basic level, a random laser is precisely what its name implies; random. It's random in the spectrum of light it produces and in the way that light is emitted, making what could be an extremely versatile laser ...

X-rays interact weakly with matter. This is their greatest strength for many applications, but also a fundamental weakness for others. In particular the fields of nonlinear optics and quantum optics, mainstays for both fundamental ...

A large-scale genetic and modelling study of Streptococcus pneumoniae has provided new insight into how recently-introduced vaccines have eliminated many strains from the species, and the diverse ways in which the remaining ...

Researchers at ETH Zurich have developed a miniature device capable of producing laser-like beams of a particular kind of electromagnetic wave called a surface plasmon. Surface plasmons can be focused much more tightly than ...

Scientists at the National Institute of Standards and Technology (NIST) have developed the first miniature laser in which the light is guided along the floor of an open metallic trench. The laser could act as a nanoscale ...

Researchers have demonstrated the first laser cavity that can confine and propagate light in any shape imaginable, even pathways with sharp bends and angles. The new cavity, called a topological cavity, could enable laser ...
